Story behind the photograph

I was passing Sydney Town Hall when I have noticed a skateboarder sitting on the ornate balustrade and he was having his lunch. Bent almost in half he was looking somewhere as if he was trying to spot someone. At the same time there was considerable group of people at the pedestrian crossing and I have noticed that practically everyone was turned away from the skateboarder. With a semi circular space created between the young man and the rest of the crowd. Town Hall is a busy place at lunchtime and it was rather odd there were no people walking towards me and the skateboarder.
